Infrared and X-Ray Evidence for Circumstellar Grain Destruction by the Blast Wave of Supernova 1987A
E. Dwek, R. G. Arendt, P. Bouchet +10
Multiwavelength observations of supernova remnant (SNR) 1987A show that its morphology and luminosity are rapidly changing at X-ray, optical, infrared, and radio wavelengths as the…
The ACS Fornax Cluster Survey. II. The Central Brightness Profiles of Early-Type Galaxies: A Characteristic Radius on Nuclear Scales and the Transition from Central Luminosity Deficit to Excess
Patrick Cote, Laura Ferrarese, Andres Jordan +9
We analyse HST surface brightness profiles for 143 early-type galaxies in the Virgo and Fornax Clusters. Sersic models provide accurate descriptions of the global profiles with a n…
Oscillations in Procyon A: First results from a multi-site campaign
S. Hekker, T. Arentoft, H. Kjeldsen +45
Procyon A is a bright F5IV star in a binary system. Although the distance, mass and angular diameter of this star are all known with high precision, the exact evolutionary state is…
Mid-Infrared Photometry and Spectra of Three High Mass Protostellar Candidates at IRAS 18151-1208 and IRAS 20343+4129
M. F. Campbell, T. K. Sridharan, H. Beuther +8
We present arcsecond-scale mid-ir photometry (in the 10.5 micron N band and at 24.8 microns), and low resolution spectra in the N band (R~100) of a candidate high mass protostellar…
The compact group--fossil group connection: observations of a massive compact group at z=0.22
Claudia L. Mendes de Oliveira, Eleazar R. Carrasco
It has been suggested that fossil groups could be the cannibalized remains of compact groups, that lost energy through tidal friction. However, in the nearby universe, compact grou…
The star pile in Abell 545
R. Salinas, T. Richtler, A. J. Romanowsky +2
Context:Struble (1988) found what appeared to be a cD halo without cD galaxy in the center of the galaxy cluster Abell 545. This remarkable feature has been passed almost unnoticed…
